Instead of clearing the entire buffer, we only need to wipe out the

that end up spamming clears.

GPU/HW: Further tweaks to replacement alpha handling
...
We can't simply clear the alpha channel unconditionally here, because that
would result in any black pixels with zero alpha being transparency-culled.
Instead, we set it to a minimum value (2/255 in case of rounding error, I
don't trust drivers here) so that transparent polygons in the source still
set bit 15 to zero in the framebuffer, but are not transparency-culled.
Silent Hill needs it to be zero, I'm not aware of anything that needs
specific values yet. If it did, we'd need a different dumping technique.

Hopefully work around sampling precision issues in older AMD drivers

This is the value for bit15 in the framebuffer. Silent Hill

technique.

Consistency. Mali ends up ever-so-slightly faster with sample versus
texel loads, apparently.

GPU/TextureCache: Map replacement non-255 alpha to fully transparent

That way if during the scaling process you end up with interpolated
colours, the cutout alpha is preserved.
Ideally we'd blend it, but that tends to create more problems than it
solves on PSX.

Also rewrite shaders to improve blurring around edges of 3D objects

As a trade-off, the background does blur slightly less, but (imo)
it looks better overall, since you'll notice the foreground being
blurred much more than the background.
